Since the game is in beta phase and I'm a total noob at the game I find it natural to play with bots. My bot match consists of 3 hard bots on my team and 4 easy bots on the opposite team, plus me of course.
Well, with this setting the bots always seem to pick the same heroes every time. In every game I have a bane, a Kunkka, a Sven and always a vengeful spirit. I have been playing the game for 2 weeks and not once have I seen the bots pick a hero such as beastmaster, wisp or clockwork, they always select the same heroes. I'd like to practice with other heroes than these and learn how to work with other heroes except Sven.
How do bots in dota 2 pick their heroes? Why don't they pick other heroes besides the ones mentioned?
